It moves up and opens beverage outlet 23, so that coffee liquid can be flowed out from beverage outlet 23, and work as jack-up suffered by valve body 91
Power disappears (such as after removing grinding chamber 2 from base 1), and elastic component (93) 93 can extend, and make valve body 91 with diaphragm seal
92 move down and close beverage outlet 23, so that coffee raffinate be avoided to flow out from beverage outlet 23.Without loss of generality, the present embodiment
In, which is compressed spring；Certainly, in other embodiments, which can also but be not limited to
Resilient sleeve etc..In addition, liquid valve 9 can also be the control valve of other structures it should also be noted that, in other embodiments,
As long as being able to achieve the opening and closing of beverage outlet 23.
The present invention also proposes a kind of coffee preparation method, which is carried out using the coffee machine of previous embodiment
Coffee preparation.
Referring to Fig. 3, in an embodiment of the present invention, the coffee preparation method the following steps are included:
Step S1, grinding knife group is by the intracavitary coffee bean grinding of investment mill beans at ground coffee；
Step S2, for hot-water supply device to the mill intracavitary injection hot water of beans, mill beans are intracavitary after the hot water of injection preset volume,
It is rectangular at pressure space thereon, pressure is carried out with the intracavitary coffee liquid of opposite grinding beans and is brewed.
In the present embodiment, grinding knife group has the function of that ground coffee beans and stirring are infused coffee simultaneously.By coffee bean
It, can be by motor driven grinding knife group high speed rotation, and by coffee bean grinding at ground coffee after investment mill beans are intracavitary.Hereafter, may be used
By hot-water supply device to the mill intracavitary injection hot water of beans, to infuse coffee.It, can since lid seals the top of mill beans chamber
During injecting hot water, the outle water rate of hot-water supply device is set to be greater than the rate of output water of Coffee screen net, and when mill beans chamber
When interior water covers filter opening part (preset volume) in Coffee screen net, pressure space is formed at the top in Coffee screen net, pair
Coffee carries out pressure and brews, so that ground coffee is sufficiently infiltrated, so that the coffee for brewing out is more dense.It should be noted that
It, can be by motor driven grinding knife group low speed rotation, to accelerate the wetting velocity of ground coffee during infusing coffee.
In the present embodiment, further, the air pressure in the pressure space is greater than or equal to 1bar and is less than or equal to
2bar, it is excessive to avoid the air pressure in the pressure space, it will be understood that pressure crosses the water outlet that conference quickly increases Coffee screen net
Rate influences the infiltrating time of ground coffee.In addition, brewing effect, the air pressure in the pressure space to obtain effective pressure
Cannot be too small, in this way, the air pressure range in the pressure space is typically limited to 1.3bar~1.7bar.It should be noted that
For determining the coffee machine of model, the gross area equipped with filter opening and filter opening mesh number of Coffee screen net be usually it is set, from
And the throttling action of Coffee screen net is set, in this case, water inlet speed needed for hot-water supply device being obtained by experiment
Rate is come so that the pressure space has suitable air pressure.
In the present embodiment, further, upon step s 2, further comprise the steps of:
Step S3, hot-water supply device is to the mill intracavitary injection air of beans, to increase or keep the air pressure in pressure space.
It is appreciated that hot-water supply device will not be ad infinitum to the mill intracavitary injection hot water of beans, when hot-water supply device is to mill
After intracavitary the injected hot water amount of beans reaches preset value, hot-water supply device will stop filling the water.At this point, to extend coffee machine pair
The pressure brewing time of coffee liquid in the present embodiment, after hot-water supply device will stop water filling, also continues supplying by hot water
Answer device to the mill intracavitary injection air of beans, to increase or keep the air pressure in the pressure space, in this way, coffee machine can be promoted
Effect is brewed to the pressure of coffee liquid.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all at this
Under the inventive concept of invention, using equivalent structure transformation made by description of the invention and accompanying drawing content, or directly/use indirectly
It is included in other related technical areas in scope of patent protection of the invention.
